When creating the On-Premise IT Roundtable podcast, we had a lot of inspiration. Here are some of our favorite IT podcasts that keep motivating us to make our own content even better!
Automating and Enforcing a Consistent vSphere Configuration
Chris Wahl of Wahl Network comments: It’s always a good idea to enforce consistency for any environment as it leads to a predictable stack that better aligns architecture to reality. As a bit of a self-challenge, I wanted to write a set of PowerShell scripts that would use a defined list of configuration state values to […]
When To Use Multiple Subnet iSCSI Network Design
Chris Wahl of Wahl Network comments: I’ve had a few readers send in questions around their iSCSI network design as it pertains to an ESXi environment. The main confusion is when to use multiple subnets for iSCSI, as opposed to VMkernel binding, based on various vendor documents and best practice guides. Let’s start with what VMware […]
DIY Project: Replacing Stock Cisco SG300-52 Fans With Silence
Chris Wahl of Wahl Network comments: My latest switch, the Cisco SG300-52, isn’t all that loud in the grand scheme of things. In fact, you can read about my experience with the switch, including noise meters, here. However, I like to keep my home office as quiet as possible because it shares space with my […]
A Caveat to Multi-Cluster VDS Design with NSX
Chris Wahl of Wahl Network comments: One of the many design decisions surrounding an NSX implementation concerns the distributed switch (VDS) and how far it should stretch. Many folks create one large VDS and stretch it across clusters for simplicity’s sake, which is fine. Be aware, however, that VMs can be manually pushed around from […]
Working with NSX — Layer 2 Bridging
Chris Wahl of Wahl Network comments: Not all virtual networks are going to be connected to the rest of the network in the exact same way; some Logical Switches, in fact, will want to talk directly over layer 2 to an existing VLAN-backed port group, or need to reach a gateway or service interface that […]
Applying New IP Addresses to vCenter, ESXi Hosts, and Plugins
Chris Wahl of Wahl Network comments: The first thing I wanted to look at was my vCenter plugin URLs. These are the addresses used to talk with the plugin. If they were hard coded using an IP address, they’d need to be updated to either a new IP address or a DNS name. I figured […]
How vSphere APIs for IO Filtering (VAIO) Changes Everything
Chris Wahl of Wahl Network comments: During this year’s US based VMworld 2014 conference, I had the pleasure of sitting down with the Tech Field Day Extra at VMworld crew to hear a variety of vendors discuss their products and solutions. One such company was SanDisk, or more specifically, the FlashSoft folks, around their collaboration […]
Double VCDX (DCV & NV) — What Does It All Mean?
Wahl Network comments: The VMware Certified Design Expert (VCDX) directory was recently updated with a new wave of candidates that have successfully participated in the Network Virtualization track. I am very happy to say that I am one of those folks who successfully went through the process and am now a double VCDX (data center […]
Protecting your Synology NAS from SynoLocker
Chris Wahl of Wahl Network comments: Just a quick public service announcement. Unless you’ve been under a rock, you’ve heard about a group called SynoLocker that has been exploiting folks for cash by maliciously encrypting data on Synology NAS boxes. Here is the official news page from Synology on it. I happen to run 3 […]
